摘要：

The ultrafine NiO/doped CeO2 (Ce0.8Gd0.2O1.9) compound powders were synthesized through the combustion of a citrate/nitrate gel. X-ray diffraction (XRD) and transmission electron microscopy (TEM) results show that this method is effective to prepare uniform NiO/Ce0.8Gd0.2O1.9 double phase compound powders. Moreover, the appropriate molar ratio of citric acid to rare earth metal ions (MRCM) in the precursors has a strong influence on forming a cross-linked framework, moderate oxygen element in gel and employing steady combustion. When the molar ratio of citric acid to metal ions is equal to 1.5, the compound powders with fine and homogeneous particles of about 13-18 nm were obtained. (C) 2003 Elsevier B.V.
